The last model (Pismo) with FireWire ports has internal support for AirPort (not Extreme) and will work with any AirPort Base Station (including Extreme.) If you have an earlier model, you can get a PCMCIA wireless card like the lucent card mentioned above, and it will also work with any AirPort Base Station.
